The CLC position has always been to reduce it to 360 hours to qualify, up to 50 weeks. That was our position and is still our position. This bill is improving access in terms of access to benefits by reducing it to 360 hours, but it doesn't provide for increasing it up to 50 weeks.
Now, in terms of costing up to 50 weeks, as I said earlier, in order to estimate how much it would cost, you need to factor in how much of that 50 weeks is going to be used. As we know, in order to do that calculation, you need to know how many have or will have exhausted their benefits, and we don't have that information. We know that not all Canadians will use those 50 weeks. Currently, we estimate the average is about 38 weeks, so if we do calculations based on that, we can come up with an estimate, but we don't have the factors, the information, that is required in order to make that estimate. That's one thing.
The second thing I would like to ask is on mechanisms. You said the system has been set in place so that over time it balances the account. But when does that start? Is it going to go retroactive to when that system was implemented? Is the $57 billion--
